A dash means the vendor has not published a feature list — which is not the same as the feature being unavailable.
How they handle UK obligations
Checked against the vendor's own documentation or HMRC's published list. A dash means we have not verified it — never that it is missing.

Rungs are matched by position in each vendor’s own line-up, not by what the tiers include — an entry plan on one side may cover more than the other. Prices exclude VAT unless stated, and per-seat plans are quoted per seat. Always confirm on the vendor’s own site.
